dim-vector.h (ndims): do not return a reference to the rep.

* dim-vector.h (ndims): this methods was only made public recently
with dcee67d28570 and is not used anywhere else.  It would expose
the rep for no gain, so always return the int by copy.
* dim-vector.cc: access the ndims on rep directly.
